構成となっている。2. Description of the Related Art A conventional balun coil has a structure in which four windings N 1 , N 2 , N 3 and N 4 are wound around a toroidal core 1 as shown in FIG. The configuration is as shown in the figure. As another conventional technique, as shown in FIG. 8 (see Japanese Utility Model Laid-Open No. 59-123317), two winding grooves fixed to the terminal plate 3 in which the terminal pins 2 are planted are provided. Two windings N 1 , N 3 and N 2 , N 4 are closely wound in each winding groove of the drum-shaped core 4 and covered with a shield case 5. As a result, as in the case of the above example, the configuration of the connection shown in FIG. 7 is obtained.

The stability is structurally poor just by connecting the lead wire of the to the printed circuit part by soldering or the like, and the toroidal core 1 is fixed to the printed circuit board with an adhesive.
Alternatively, it was necessary to fix it with fixing parts.

た。Further, in the latter conventional example, since the two winding groove positions are different from the positions of the terminal pins 2 for connection to other circuits, the lead wire of the winding at a position far from the terminal plate becomes long. , The lengths of the lead wires are different, the inductance values of the windings N 1 , N 2 and N 3 , N 4 are not the same, and the balance is lost particularly in the high frequency band, and the characteristics are deteriorated. Furthermore, since the winding groove is on the upper and lower sides, when winding using an automatic winding / wiring machine, the leader wire of the winding wound in the upper winding groove should be In order to make the circuit configuration shown in Fig. 7 so as not to break the wire when it is wound,
N 1, N 3, N 2 , and the windings in the order of N 4, must be divided in each case winding time required for winding and wiring had been increased.
